A Linear-Time Recognition Algorithm for P4-Reducible Graphs
نویسندگان
چکیده
The P,-reducible graphs are a natural generalization of the well-known class of cographs, with applications to scheduling, computational semantics, and clustering. More precisely, the Pa-reducible graphs are exactly the graphs none of whose vertices belong to more than one chordless path with three edges. A remarkable property of P,-reducible graphs is their unique tree representation up to isomorphism. In this paper we present a linear-time algorithm to recognize P,-reducible graphs and to construct their corresponding tree representation.

On Some Cograph Extensions and Their Algorithms
This paper reviews some classes of graphs related to cographs. The characterization of cographs by which there is no induced path on three edges (P4) is relaxed in various ways. Considered are classes of graphs that are uniquely representable by trees. Three such classes studied here are: P4-reducible, P4-sparse and P4-extendible graphs. In addition, we show that the class of P4-lite graphs has...
متن کاملA Simple Linear Time LexBFS Cograph Recognition Algorithm
Recently lexicographic breadth first search (LexBFS) has been shown to be a very powerful tool for the development of linear time, easily implementable recognition algorithms for various families of graphs. In this paper, we add to this work by producing a simple two LexBFS sweep algorithm to recognize the family of cographs. This algorithm extends to other related graph families such as P4-red...
متن کاملGrundy number on P4-classes
In this article, we define a new class of graphs, the fat-extended P4-laden graphs, and we show a polynomial time algorithm to determine the Grundy number of the graphs in this class. This result implies that the Grundy number can be found in polynomial time for any graph of the following classes: P4-reducible, extended P4-reducible, P4-sparse, extended P4-sparse, P4-extendible, P4-lite, P4-tid...
متن کاملLinear Time Recognition of P4-Indifferent Graphs
A simple graph is P4-indifferent if it admits a total order < on its nodes such that every chordless path with nodes a, b, c, d and edges ab, bc, cd has a < b < c < d or a > b > c > d. P4-indifferent graphs generalize indifferent graphs and are perfectly orderable. Recently, Hoàng, Maffray and Noy gave a characterization of P4-indifferent graphs in terms of forbidden induced subgraphs. We clari...
متن کاملSplit-Perfect Graphs: Characterizations and Algorithmic Use
Two graphs G and H with the same vertex set V are P4-isomorphic if every four vertices {a, b, c, d} ⊆ V induce a chordless path (denoted by P4) in G if and only if they induce a P4 in H. We call a graph split-perfect if it is P4-isomorphic to a split graph (i.e., a graph being partitionable into a clique and a stable set). This paper characterizes the new class of split-perfect graphs using the...
